The research is based on Erdtman's method, which involves analyzing the ratio between the polar axis (P) and the equatorial diameter (E), using precise morphological criteria to determine pollen grain shape. The results reveal a variety of palynological forms, with a predominance of spheroidal prolate, suboblate, and prolate types. Other forms, however, were observed only rarely or not at all during the study.enSpartieum junceum L, pollen, morphological diversity, Tébessa.Thesis
